How to Display a Subscription Confirmation Message After Form Submission in React

Are you trying to create a form in React that displays a confirmation message after a user subscribes to a newsletter? If so, you're not alone! Many new React developers find themselves facing this common issue. Let’s break it down and walk through the process step-by-step, ensuring you can easily display a message like “You are now subscribed to {SUBSCRIPTION}.”

Understanding the Problem

You have a form that captures the user's subscription preference. However, when they submit the form, you encounter the dreaded message reading “You are now subscribed to [object Object].” This happens because the code is incorrectly trying to join an object with a string, which leads to the default [object Object] outcome.

The Solution

To resolve this problem, we need to ensure that the correct property of the object is accessed and displayed. Below, I’ll break down the corrected approach:

Step 1: Update the handleSubmit Method

Instead of trying to display the entire user object, we only need the newsletter property from the object. Here’s how to modify the handleSubmit method:

Step 2: Update State Correctly in handleNewsletterInput

When the user types into the input field, we should ensure that the component's state updates correctly. If the reference of the user object stays the same, React won’t detect any changes. Use the spread operator to create a new object reference:

Conclusion

By following these steps, not only will you fix the issue of the incorrect alert message, but you’ll also have a more robust React form component. Now, when a user submits their newsletter choice, they will receive a clear confirmation message that enhances user experience.

With these adjustments, you can confidently handle form submissions and give users feedback that they’ve successfully subscribed to their newsletter of choice!
